Anal fissure [edit on Wikidata] An anal fissure or rectal fissure is a break or tear in the skin of the anal canal. Anal fissures may be noticed by bright red anal bleeding on toilet paper, sometimes in the toilet. If acute they may cause pain after defecation but with chronic fissures pain intensity is often less. Anal fissures usually extend from the anal opening and are usually located posteriorly in the midline, probably because of the relatively unsupported nature and poor perfusion of the anal wall in that location.

Anal Fissure Symptoms, Treatment Relief, and Cure An anal fissure is a cut or tear occurring in the anus (the opening through which stool passes out of the body) that extends upwards into the anal canal. Fissures are a common condition of the anus and anal canal and are responsible for 6% to 15% of the visits to a colon and rectal (colorectal) surgeon. They affect men and women equally and both the young and the old. Fissures usually cause pain during bowel movements that often is severe. Anal fissure is the most common cause of rectal bleeding in infancy. Anal fissures occur in the specialized tissue that lines the anus and anal canal, called anoderm. At a line just inside the anus (referred to as the anal verge or intersphincteric groove) the skin (dermis) of the inner buttocks changes to anoderm.
